Smooth predictable riding isn’t just a matter of style...here the word survival comes to mind! If unpredictability is the only predictable part of your riding style, you are a hazard to yourself and everyone else who has the misfortune to ride with you.

Call out Slowing, Stopping, Passing on Left, Passing on Right (pass on right only in emergencies )

This habit will get you in real trouble. This is a good way to test your ability to do cartwheels if you don't adhere to this rule. Some people do it from lack of concentration, others may just not know any better, but sooner or later they'll crash. There is no recovery from a front wheel deflection. 

Sometimes steady doesn’t just mean speed. It means steady pressure on the pedals…uphill or downhill, headwind or tailwind.

When you are following, announce oncoming traffic from the rear…in this case others should relay this info toward the front... and end their conversation and single up.

Signaling with hands or voice lets everyone (vehicles and riders) know your intentions.

Learn to be comfortable looking around or through the riders ahead of you. This will allow you to see things that are developing in front of the group.

If you get separated at intersections, as a matter of courtesy, the lead group should soft pedal until the rest have rejoined. Another note here is that if you are the one who will be caught by the light, don't run the red light to maintain contact.

It comes "biker wannabe's" time to take his/her pull and the pace is getting up there.  The thoughts running through his/her mind is, "I need to show these guys that I can pull 2 mph faster than everyone else has been pulling."  They go to the front and hammer.  Legs begin to burn after a monumental pull...now it's time to pull over and let some "lesser" rider take a turn.  Well, the "lesser" biker is all refreshed after tagging on a wheel and is ready to punch it up another notch. 

The first and probably most important tip is to ride responsibly. Follow the traffic rules yourself! I’m sure you’ve all witnessed a cyclist who blatantly ignored traffic laws. Believe me, there’s nothing that upsets a motorist more than to see a cyclist darting around cars through intersections, running stop lights, weaving around in the center of the road, etc.

Stay as near to the right side of the roadway as is practical, unless making a left hand turn, avoiding hazards in the road, or when the lane is just too narrow to share safely with a motor vehicle.  I recently observed a presumably novice rider spinning very slowly up a hill approximately 4 feet from the roadside, in a lane that had ample room for both him and the motorists.   This occurred at 5 p.m. and traffic was backed up about 8 cars deep behind him.

Impeding the flow of traffic creates bad blood.  I also find that chatting with your training partner leaves you distracted to what is occurring around you.  By the time you realize there is a "car back" it may be literally behind you before you are able to line up single file.

Ride with Safety and Courtesy as your guide

Watch For Traffic Coming From The Rear.
Leave A Gap for Cars.
Wait At Turns.
Move Off the Road When You Stop.
Courtesy dictates that you single up when cars are trying to pass you if the lane is wide enough for them to safely do so.
